用于Android应用程序的Gmail的OAuthentication错误

我想在Android上为Gmail创建一个客户端应用程序（我已经看到有很多关于此问题的问题）。用于Android应用程序的Gmail的OAuthentication错误

（我见过类似这样的问题：How to integrate Gmail Api in android app但我的问题是不是与SHA1键）

我使用的Andorid的开发者网站上给出的链接：https://developers.google.com/gmail/api/quickstart/android

我在此基础上开展了第一项活动，并在Google开发者控制台中创建了API访问权限。

我使用usingOAuth拿到证书，

mCredential = GoogleAccountCredential.usingOAuth2(
      getApplicationContext(), Arrays.asList(SCOPES)) 
      .setBackOff(new ExponentialBackOff());

我看见了在我的手机配置的邮件ID列表，当我选择一个我称之为异步方法服务：

public MakeRequestTask(GoogleAccountCredential credential) { 
     HttpTransport transport = AndroidHttp.newCompatibleTransport(); 
     JsonFactory jsonFactory = JacksonFactory.getDefaultInstance(); 
     mService = new com.google.api.services.gmail.Gmail.Builder(
       transport, jsonFactory, credential) 
       .setApplicationName("mailclient") 
       .build(); 
    }

这只能在异步服务的onCancelled（）方法，并提供误差

该应用程序试图连接到的网址是不是适当的一个

https://console.developers.google.com/apis/api/gmail/overview?project=608941808256

我不知道我在做什么错在这里，我认为我必须做的唯一事情是给无论是API或客户端ID在应用程序的某处。但我不确定我应该在哪里给这些常量？

请检查您的Gmail API和其他API是否已在Google Developers Console中启用。要启用它，请从API菜单中选择Gmail API，然后请点击启用（如下图所示）。

此外，您可能还需要检查这个GitHub post或本SO post。

对于相同的代码，当我在android 2.2上运行它时（在它是android 1.4之前），我已经开始工作了。我不确定问题是什么，我应该看看。但现在我有它的工作。 –
